Modular double-stator permanent magnet linear motor and motor module employing same

The invention discloses a modular double-stator permanent magnet linear motor and a motor module employing the same. The modular double-stator permanent magnet linear motor comprises a rotor (1) and double stators (2), wherein an air gap is formed between the rotor (1) and the double stators (2); the double stators (2) are distributed on the upper side and the lower side of the rotor (1) respectively and are staggered from each other by half of a stator polar distance; the rotor (1) comprises rotor modules (10); in actual application, the quantity of the rotor modules (10) of the rotor (1) is determined and adjusted according to a force output requirement. The motor has the advantages of simple and reliable structure, counter electromotive force sine, large thrust, low thrust fluctuation, high efficiency, high fault tolerance and the like, and the quantity of the needed rotor modules can be conveniently set in the actual application according to the force output requirement.
